- **A shallow clone of a big repository works, and quickly (#137).** `oxy clone --depth 0` of the VS Code history failed after eleven minutes ("object … not found"): the blobs of the state's binary files are named only by the changes that set them, which a depth-0 clone does not take, so nothing brought them. They are now fetched with the checkpoint (in parts), or left to be fetched on read under `--max-blob`. The checkpoint itself was stored object by object, each written loose and flushed (57,498 objects at 27 a second); it is now stored in one batch, as a fetch's objects are.

- **A push no longer passes a proxy's request limit (#133).** A push to a hub behind Cloudflare, which takes at most 100 MB in one request, was refused `HTTP 413` with Cloudflare's HTML page printed raw: parts of a long push were about 256 MiB, and one change's blobs went in one request however many there were. Parts are now about 64 MiB (`push.batch-bytes`), a part whose blobs pass that sends them first in parts of objects alone, an HTML error page is shown by its title, and a 413 says how to push in smaller parts.

- **A keyless agent's grant survives its owner's key rotation (#135).** Every delegation an owner adds or removes renews their identity, and a repository that names the newest key as `author.key` read every change their agent sealed as INVALID ("key … is neither the author nor a delegate"), and its pushes were refused, because the agent's grant was signed by the owner's earlier key. A grant by a key the author's identity was rotated or renewed from now counts when it was made before that rotation; one an old key made after it does not.
